What not to do is usually a better question. There are lots of little things that get lost in the big ones. You know that little paint touch up that you'll always get to later? Guess what it's later. My month and a half of open window weather seem to be drawing to a close so before I slam and lock them I may as well see what shape they're in. It's a no brainer to clean the woodstove and fireplace that should be done already...duh. Uh what else?
